Powered by your ContiSX Smart Account
Every Android phone is powered by a Google account. Every ContiSX Phone is powered by a ContiSX Smart Account — one secure, self-custodied identity that signs you in, holds your assets, and moves value to anyone, anywhere.
Secure the communication. Keep the control.
ContiSX lets organisations communicate securely without surrendering control of their identity, encryption keys, access permissions or infrastructure to an external service provider.
Unlike platforms that depend on centrally managed databases, ContiSX separates communication from the infrastructure used to manage identity and authority. Encrypted communications stay private, while the institution retains control over who can access the network, what each user can do, and how compromised accounts or devices are handled.
With ContiSX Phone you get end-to-end secure communication at the blockchain level — across messaging, voice and video — with no eavesdropping or tampering, guaranteed by cryptographic encryption.
Secure communication
Protect sensitive organisational communications across:
- Encrypted voice & video calls
- Secure instant messaging
- Protected email & attachments
- Private group & operational comms
- Collaboration between authorised personnel
Sovereign control
The institution retains authority over:
- Digital identities
- Encryption keys
- User permissions
- Device access
Rapid response
If a device is lost, stolen or compromised, its access can be revoked across the organisation in about four seconds.
The system terminates active sessions, rejects the compromised device and removes undelivered messages tied to its revoked credentials.
ContiSX Phones enable secure mobile enterprise communication anywhere and at all times — so teams, wherever they are, can confidently chat, talk and video securely.
Built for high-consequence environments
